Brief Patent Description - Full Patent Description - Patent Application Claims
CLAIM OF PRIORITY [0001] The present application claims priority from Japanese application serial no. 2005-049921, filed on Feb. 25, 2005, the content of which is hereby incorporated by reference into this application. FIELD OF THE INVENTION [0002] The present invention relates to signaling for traffic control of a vehicle such as a railway, monorail, LRT (Light Rail Transit), AGT (Automated Guided Train) and cars. BACKGROUND OF THE INVENTION [0003] A signaling system has been developed in the field of railway industry. This system uses an interlocking device as a core of the protection system wherein a track circuit for detecting the train occupied position, a point device used for operation and locking of the point and a signal device for turning on the signal lamp to notify the operator of the permission or non-permission of entry of the train are interlocked to ensure that the train is prevented from entering the route where collision or derailment may occur. [0004] As disclosed in Official Gazette of Japanese Patent hei 7 (1995)-41840, a technique has been developed in recent years, wherein the train position detected by an on-train apparatus is captured by radio, and the point device and signal device installed in the train are interlocked and controlled, based on this train position. [0005] According to another technique having been disclosed in Japanese Patent Laid-open No. 2004-133585, the information on the position of a train is sent to other trains by radio, and the train is controlled, based on the position information sent by radio from other trains. SUMMARY OF INVENTION [0006] In the track circuit, a rail is subjected to electrical insulation, and a power source is connected to one side, while a relay is connected to the other side, whereby a short circuit between rails caused by a train is detected. The problem with this arrangement is found in the high maintenance cost. An interlocking device is provided with the input/output device for working with the wayside equipment including all track circuit devices, all point devices and all signal devices. Said devices are interlocked to avoid possible collision with the train or derailment. In this track circuit, the logic for providing such control operations is built in the relays and electronic computers. The problem with this method lies in a high cost in designing and manufacturing this track circuit, and a high cost in manufacturing and installing the wiring used for connection between the track circuit and wayside equipment. [0007] In the technique developed in recent years, the control apparatus of the wayside equipment is required to contain a communication means for acquiring the position information from a train, and a logic section and input/output means for providing control under interlock between the point device and signal device to avoid possible collision or derailment of the train, based on the position information from the train. This arrangement increases the cost of designing and manufacturing the apparatus and the base station for relaying the communication between the apparatus and train. [0008] The aforementioned problems are found not only in the rolling stock, but also in the automobiles traveling along the predetermined route. [0009] The object of the present invention is to provide a signaling system characterized by reduced designing and manufacturing costs. [0010] The present invention provides a signaling system wherein the protection of a train traveling within a predetermined section is ensured by a telegram, and the telegram patrols a train or wayside equipment located within the predetermined section and has a block occupancy information for assigning the right of being occupied by a train to each of the blocks formed of a plurality of divisions of the aforementioned section. Further, this telegram has the member list information represented in the order of patrol of the identification information of the train and wayside equipment. [0011] The present invention provides a train comprising: [0012] a traffic control section for storing the operation planning information of a train and for generating the route request information for requesting permission for the train to enter the route, based on the operation planning information; [0013] a train protection section capable of generating a telegram, determining, based on this telegram, whether or not permission to enter should be granted to the aforementioned train, and exchanging the aforementioned telegram with other trains or wayside equipment; [0014] a speed control section for controlling the train travel; [0015] wherein the aforementioned telegram patrols a train and wayside equipment located within a predetermined section and within the section adjacent thereto; and contains: [0016] block occupancy information for assigning the right of being occupied by a train to each of the blocks formed of a plurality of divisions of the aforementioned section; and [0017] member list information represented in the order of patrol of the identification information of the train and wayside equipment; [0018] wherein, based on the route request information from the traffic control section and the telegram received from another train or wayside equipment, the aforementioned train protection section determines whether or not permission to enter should be granted to the aforementioned train, sends the updated telegram with other another train or wayside equipment, and outputs the result of decision to the aforementioned train control section. [0019] The present invention provides a point protection apparatus provided with: [0020] a communication section for exchanging the telegram containing: Continue reading about Signaling system...
